56 years ago, on 19 April 1961, Cuban revolutionary and popular militias put an end to the mercenary aggression armed, financed and equipped by the US government that on April 17 had landed on the shores of the Bay of Pigs. This military defeat at Playa Giron, within 72 hours of the invasion, destroyed the target plans of imperialism to establish a “beach-head” from which to declare an illegitimate government of Cuba. It implied a major blow to the objective of defeating the Revolution. Army troops and popular militias, under the direct leadership of Fidel Castro, put a courageous resistance against the invaders and against the military support they enjoyed from the US with air and sea capabilities. They captured over 1000 prisoners among the mercenaries and demonstrated the combat power and readiness of a people when they are defending a true and legitimate revolution.
